No way to see long running API response

The current CLI provides waiting by default for each command. When --no-wait option is used, the CLI immediately returns back without displaying anything to the customer. If this is a long running action, the customer has no ability to retrieve the status of async command. Each command would need to use --debug to see 'Azure-AsyncOperation' header returned. This creates poor customer experience.

The proposal is to enhance command behavior for --no-wait.
Specifically, when the customer asks not to wait for the final result, the CLI should print a header back.
